Abstract
Des films pré-étirés peuvent être utilisés pour augmenter la vitesse à laquelle des charges peuvent être emballées et pour minimiser l'effort nécessaire lorsque l'on utilise un film à main classique. Toutefois, les bords des films pré-étirés s'endommagent facilement, ce qui peut causer une déchirure ou une défaillance du film en cours d'utilisation. Cette invention porte sur des dispositifs, des systèmes et des procédés pour plier les bords du film, ce qui permet d'obtenir un film moins susceptible de s'endommager et plus facile à utiliser.
